Mail server using Postfix, Dovecot, Mysql... Postfix virtual maps doesn't work??

[tarasbuljba]

I have followed this guide

http://www.howtoforge.com/virtual-us...ysql-centos4.5

I change a little at me and edited custom postfix file as it is there, dovecot work, squiremail work and postfix work when i have no virtual aliases! When i add virtual things to postfix then it doesn't send/receive mail

In my configuration when i have this commented out all work fine and no errors, when it is use then postfix doesn't work

#virtual_mailbox_domains = mysql:$config_directory/mysql_virtual_domains_maps.cf
#virtual_mailbox_base = /var/vmail
#virtual_mailbox_maps = mysql:$config_directory/mysql_virtual_mailbox_maps.cf
#virtual_alias_maps = mysql:$config_directory/mysql_virtual_alias_maps.cf
#virtual_minimum_uid = 5000
#virtual_uid_maps = static:5000
#virtual_gid_maps = static:5000
#virtual_maildir_limit_message = "The user you are trying to reach is over quota."
#virtual_overquota_bounce = yes
#virtual_mailbox_extended = yes
#virtual_create_maildirsize = yes

Files i use for it are from that guide i posted link above... does anyone have any idea about why is this like that? I spent hours and hours trying all ways... Now i have dovecot and other running for nothing as this doesn't work

Thanks!

What do you see in the logs when postfix stops working ?

[tarasbuljba]

No no, postfix doesn't stop working, it loads normal as like without virtual things, and logs are empty...

I tested a bit more and it seems that problem is in virtual_mailbox_domains, virtual_alias_maps, virtual_mailbox_maps files because only they are commented now and postfix work, other i didn't comment... now i dunno if it is files from that guide or something wrong in that line? :O

EDIT: I forgot to add, when i have that virtual stuff mails seems to stay in quote on serv, when i comment them out later and restart postfix i receive emails sent by eg. forum on serv

You can run strace to see what is actually happening what is causing postfix to hung and not deliver.

I get this for strace -p on main master pid

read(10, "\0", 1)                       = 1

I noticed something else, when i use that virtual things with grep postfix i get

root     22887  0.0  0.1   6704  1748 ?        Ss   19:21   0:00 /usr/libexec/postfix/master
postfix  22889  0.0  0.1   6768  1736 ?        S    19:21   0:00 pickup -l -t fifo -u

And when i don't use them i get many more...

Now that is weird a bit :/

The master is unable to start the other processes that means something is hunging i cannot put my figure on it, I guess you need to run strace from when you start the process.
